7 of us stayed at Bangkok Hub Hostel. Kriengkrai was very hospitable and made us feel at home. He was kind, down to earth, and friendly. He made sure all our needs were met and was very helpful with our trip around Bangkok.
The location of the hostel is superb. It is located next to the BTS and the pier (access to Asiatique, Grand Palace, Khao San Road, museum, canal tour and temples). There are many street food vendors, a shopping center and stores around.
We all stayed in both the dorm room and private room. Overall, we felt safe and comfortable. The beds were firm but the most comfortable beds that we experienced on our trip. Air conditioning worked great. Both shared and private bathrooms were clean. With all of us, we didn't have any issues with waiting too long on using the shared bathroom. There was an onsite laundry machine. Free coffee and tea. The only improvements we could think of is to have more places to sit in the common area and maybe offer simple breakfast (pastries, cereal, and fruit). Otherwise, we would love to stay here again in the future.
